我们从蚕豆生长中观察到,每株蚕豆至少开花20朶以上,多的达到100余朵,但花朵脱落十分严重,荚果不多,一般结二、三荚、多则六、七荚、大大影响产量的提高。为探寻蚕豆落花的原因,我们从1956年即开始观察研究,1959年又在县农业试验站进行试验;已初步明确播种期与蚕豆落花的关系,现介绍如下:蚕豆开花期长,经过气候变化大。播期早迟,对落花影响很大。播期过早,前期气温高,苗稼生长发育快,开花时间提前,常常在开花时遇到各季低温,不能正常授粉,花朵脱落较多,结荚少。播期过迟,
We observed from the growth of broad bean that each faba bean at least 20 or more flowering, more than 100 to achieve more, but the flowers off is very serious, not many pods, generally knot two, three pods, as many as six or seven pods, greatly affected Increase in production. In order to find out the reasons for the falling of Vicia faba, we started to observe the study from 1956, and experimented at the County Agricultural Experiment Station in 1959. The relationship between the planting period and Vicia faba has been tentatively identified. The introduction is as follows: The Vicia faba long flowering period, after climate change Big. Sowing sooner or later, a great impact on the falling flowers. Early sowing, early high temperature, rapid growth and development of Miao Jia, early flowering time, often encountered in the season when the low-temperature flowering, pollination can not be normal, flowers shed more, less pods. Sowing too late,
